Marantz Model 50 - Silver - Black

Description

Current Feedback Amplification

Current feedback amplification is a well-known, Marantz-original circuit technology, thoughtfully designed to match the requirements of hi-res music for wide-bandwidth, high-speed reproduction. Marantz current feedback amplifiers reduce the need for phase compensation by minimizing negative feedback. This simplifies the signal path and results in excellent transient response and superb sonic transparency across the full bandwidth. Unlike conventional voltage feedback topology, current feedback also makes the power amplifier capable of driving difficult loudspeaker loads, meaning The Model 50 is the ideal amplifier for a very wide range of loudspeakers.

Hyper Dynamic Amplifier Modules (HDAM)

While many brands claim unique engineering in sensitive and analog circuits, most use commonly available integrated op-amps in critical signal paths. Those op-amps can compromise audio integrity and limit design ingenuity. Marantz developed an entirely unique replacement for integrated circuits using ultra-high-quality discrete components. Marantz HDAM circuitry outperforms traditional op-amps both in the listening room and the laboratory. Very high-speed signal handling dramatically improves bandwidth. Clever amplification design minimizes distortion and ideal layout silences noise. Ultimately, the flexibility a fully discrete solution provides the freedom to engineer the ideal basis for extraordinary performance. The Model 50 utilizes HDAM SA-3.

Marantz Musical Phono EQ

Since their first product, the Audio Consolette, Marantz has maintained their commitment to vinyl with the Marantz Musical Phono EQ stage. This version of Marantz Musical Phono EQ uses two-stage amplification, allowing less gain per stage for lower distortion. The Model 50 combines Marantz HDAM technology with JFETs in the input stage, providing high input impedance that eliminates the need for AC coupling capacitors and vastly simplifies the signal path, dramatically improving the signal purity overall.

High-Precision E-Vol Electronic Volume Control

The Model 50 uses an ultra-precise electronic volume control system that adjusts both the circuit gain and the output voltage. This system maintains high dynamic range and limits noise across a far broader volume range than traditional systems. More traditional integrated amplifiers use basic potentiometers which can suffer from poor channel balance and increasing noise and distortion over time.

Marantz SPKT 1+ Speaker terminals

Ensure a perfect bond to your loudspeaker cables with Marantz custom binding posts, which ensure ideal connectivity while shielding from inadvertent short circuits.

Discrete Headphone Amplifier

For exquisite private listening, the Model 50’s output is designed using fully discrete HDAM SA-2 circuitry to ensure your headphones sound as warm, spacious, and clear as you would expect from your loudspeakers.
